About us

　　Beijing JWGB Sci.&Tech. Co.,Ltd, located in LiGong Sci.&Tech. Building, Zhongguancun Science Park, is a premier hi-tech company focusing on nitrogen adsorption surface area and pore size distribution analyzer manufacturing. JWGB corporate is composed of R&D department, sales, post-sales ustomer service department and Shanghai branch. The goal and objectives of JWGB is to offer quality products and efficient service to customers. 　

　　JWGB plays a very special and prominent role in nitrogen adsorption instrument industry in China. Early in 2000, JWGB's engineers in Beijing Institute of Technology succeeded in a new model nitrogen adsorption analyzer R&D and manufacturing, opened a new era in nitrogen adsorption analyzer industry in China; in 2004 JWGB developed the first dynamic BET surface area analyzer in China, and stay abreast with its counterparts abroad; in 2005 dynamic pore size distribution analyzer was introduced, which was a historical breakthrough in this area.  From then on, JWGB have obtained proprietary technologies for a complete lines of dynamic nitrogen adsorption analyzers, in 2007 a huge leap forward is innovation and success in static nitrogen adsorption surface area and pore size distribution analyzer, which firmly put us in a very competitive position in international market. Based on continuing innovations and achievements in this area, JWGB boasts the initiator, innovator, and leader in nitrogen adsorption characterization industry in China.

　　JWGB's motto: continuing innovations for further development, quality as the first concern, customer's need as corporate focus. JWGB has establishedcomprehensive quality control and post-sales service systems. Based on the ongoing quality-improving products and feedback of customers, JWGB spares no efforts to deliver new equipment for materials' physical properties and even a general testing solutions to streamline research activities in institutes and enterprises. The above all combined will put us invincible in terms of technologies and products in this area.
